In Fig. 5 the half-ring d is plus and the halfring d minus when thearmatures are as shown in that figure, and the current through the lineis fromf tof; but when the armatures are moved through ninety degreesthe halfring d becomes minus and (1 plus; but as the brushes ff havechanged contact with the half-rings-that is,fis in contact with d and fwith dthe current over the line f is as before-that is, from f to f. Onthe next quarter of the revolutionthat is, when the armatures have beenmoved the second ninety degrees (or one hundred and eighty degrees fromtheir position shown in Fig. 5)the halfring d will be plus and thehalf-ring d will be minus; but the current will nevertheless befromftof, becausefis then in contact with d and f with d. On the nextquarter of the revolution the half-rings d d. again change theirpolarity, (I being minus and d plus; but the current is the same asbefore, forfis then in contact with d andf with d. In this way there aretwo pairs of currents of the same polaritythat is, in the samedirectionsent through the wire at each revolution of the armatures, andthe purpose of this arrangement of the half-rings d d and brushes ff isto cause a bell-hammer arranged between two bells and actuated by thecurrents generated by my device to strike two blows upon one bell, thentwo upon the other, for each revolution of the armatures B B.

In Fig. 13 I show two bells, 1 and 2, arranged with a bell-hammer, 3,between them, and this is a convenient arrangement of the hammer and thetwo bells, as will be readily understood without furtherdescription.When simple alternate currents are required, the half-rings d d are notnecessary;

but this arrangement, whereby I get currents in pairs, is an importantfeature of my invention.

Fig. 11 is a diagram illustrating one of my magnets with six poles, andFig. 12 with eight poles; and from the drawings it will be clear to allskilled in this art how to multiply the poles to any desired extent. InFig. 11 no advantage is derived from using a double armature, and I havetherefore indicated an ordinary armature; but while I have shown mymagnets as adapted to induce a current in the coil of an armature I donot of course limit myself to such use.

One of the chief advantages of my new apparatus is that multiplying-gearcan be dispensed with; for although I have shown such gear in Fig. 1,that is solely because I wished to indicate the medical use of myapparatus; but with my double armature each revolution will give fourcurrents with a four-pole magnet, eight currents with an eight-polemagnet, and so on, for each revolution of the armature, and consequentlyno multiplying-gear is needed for many uses of my apparatus. This is apractical matter of considerable consequence, as it greatly lessens theexpense of construction.

What I claim as my invention is-- 1. The double armature abovedescribed, composed of the two cores and the two coils, the cores beingheld together back to back, but magnetically insulated, substantially asshown.

2. In combination, the double armature B B and its two coils, themagnets A A, &c., and the electrodes (2 d and f f, whereby the currentsare sent in pairs over the line, as set forth.
